goi(): Goodness of Interpretability (GoI) index
measuring how well the E2Tree-estimated proximity matrix reconstructs
the original ensemble proximity matrix.goi_perm(): Permutation test for the GoI index to
assess statistical significance.goi_analysis(): Combined GoI analysis returning both
the observed statistic and permutation results.plot.goi_perm(): Plot method for goi_perm
objects displaying the permutation distribution.plot_e2tree_vis(): Interactive E2Tree visualization
using visNetwork with draggable nodes, zoom/pan, and
multiple layout options.plot_e2tree_click(): Interactive E2Tree plot in the R
graphics device with click-to-inspect node details.save_e2tree_html(): Save an interactive
visNetwork tree plot as a standalone HTML file.print_e2tree_summary(): Print a formatted summary of an
e2tree object.createDisMatrix: C++ backend
(CoOccurrences.cpp) with OpenMP thread-level parallelism
replaces the R-level foreach/doParallel loop;
co-occurrence normalization also moved to C++.e2tree: vectorized Wt computation using
vapply; simplified internal get_classes
helper.ePredTree: split rules are now pre-parsed once
(parse_all_splits + apply_split_rule),
eliminating repeated regex/eval(parse()) calls
during prediction.vimp: three group_by operations
consolidated into one; eval/parse
removed.split: ordSplit and catSplit
vectorized with outer().eImpurity: single-step integer matrix conversion.NumericVector +
static_cast<int>) for ranger compatibility (ranger
returns double columns for tree node assignments).ePredTree returning character instead of double
for regression trees.filter() call in
proximity_longer.R causing namespace conflict with
dplyr.NAMESPACE imports for
graphics, grDevices, and
utils.aaa_utils.R with shared internal helpers:
e2_variance(), get_ensemble_type(),
check_package().eValidation, eImpurity, and
eStoppingRules for consistency and performance.NEWS.md file to track changes to the
package.
